Recently I've had several companies inquire about getting a forklift license that applies to both Class 4 and 7. They said since they are both forklifts a class 4 training will apply equally to a class 7 license. In the past my company has had a separate training for the 4 and the class 7 forklifts. Is this right?

The reason I give the companies is that although there are some similarities, a class 4 and class 7 operate differently therefor they require different instruction.

I have not found a specific answer online, and left a message with OSHA but have not heard anything back. Your comments are much appreciated!!
